Energetic particles, such as protons, can be detected with a silicon detector. When a particle strikes a thin piece of silicon, it creates a large number of free electrons by ionizing silicon atoms. The electrons flow to an electrode on the surface of the detector, and this current is then amplified and detected. In one experiment, each incident proton creates, on average, 37,000 electrons; the electron current is amplified by a factor of 100; and the experimenters record an amplified current of 3.5 μ.Α.

X-Rays are just high energy light that can penetrate through flesh but not bones. The X-Ray machines use accelerated electrons hitting a target metal, such as copper or tungsten, generating X-Rays toward the patient. If the operator tells you that the target receives 0.8 A current, how many coulombs of charge is striking the target in 0.7 seconds?
Flying Circus of Physics Kiting during a storm. The legend that Benjamin Franklin flew a kite as a storm approached is only a legend – he was neither stupid nor suicidal. Suppose a kite string of radius 2.07 mm extends directly upward by 0.809 km and is coated with a 0.514 mm layer of water having resistivity 177 Q-m. If the potential difference between the two ends of the string is 190 MV, what is the current through the water layer? The danger is not this current but the chance that the string draws a lightning strike, which can have a current as large as 500 000 A (way beyond just being lethal). Number i Units

Flying Circus of Physics Exploding shoes. The rain-soaked shoes of a person may explode if ground current from nearby lightning vaporizes the water. The sudden conversion of water to water vapor causes a dramatic expansion that can rip apart shoes. Water has density 1000 kg/m3 and requires 2256 kJ/kg to be vaporized. If horizontal current lasts 2.26 ms and encounters water with resistivity 154 Q-m, length 14.0 cm, and vertical cross-sectional area 15.2 x 10-5 m², what average current is required to vaporize the water?

Kiting during a storm. The legend that Benjamin Franklin flew a kite as a storm approached is only a legend — he was neither stupid nor suicidal. Suppose a kite string of radius 2.10 mm extends directly upward by 0.802 km and is coated with a 0.520 mm layer of water having resistivity 155 Ω·m. If the potential difference between the two ends of the string is 176 MV, what is the current through the water layer? The danger is not this current but the chance that the string draws a lightning strike, which can have a current as large as 500 000 A (way beyond just being lethal).
The beam, consisting of electrons with constant kinetic energy and uniform density, carries a current of 1 mA. The cross-section-area of the beam is 23 mm², the electron density is 3x10^12 cm-3. If the electric current is directed to the right, what is the magnitude (m/s) and direction of the velocity of the electrons?
Energetic particles, such as protons, can be detected with a silicon detector. When a particle strikes a thin piece of silicon, it creates a large number of free electrons by ionizing silicon atoms. The electrons flow to an electrode on the surface of the detector, and this current is then amplified and detected. In one experiment, each incident proton creates, on average, 34,000 electrons; the electron current is amplified by a factor of 100; and the experimenters record an amplified current of 3.5 μA.

A Nichrome heater dissipates 520 W when the applied potential difference is 110 V and the wire temperature is 800°C. What would be the dissipation rate if the wire temperature were held at 203°C by immersing the wire in a bath of cooling oil? The applied potential difference remains the same, and a for Nichrome at 800°C is 4.0 × 104K1. Number Units

A stream of electrons with a linear number density of 3.10 x 1011 electrons/meter are accelerated from rest by a 62.0-V potential difference applied across two parallel plates. The electrons then pass through an aperture in the high voltage plate and into a current collector where the beam current is measured. Note: The mass of an electron is 9.11 x 10-31 kg.
